黑洞附近的潮汐效应

Tidal effects in the vicinity of a black hole

A. Cadez, U. Kostic, M. Calvani

摘要:

银河系中心发出不同波长的耀斑的发现代表了关于其起源的一个谜,但同时也是调查最近的超大质量黑洞环境的一个相关机会。本文将回顾我们最近关于黑洞周围低质量卫星轨道的潮汐演化及其在落入过程中的潮汐效应的一些结果。我们表明,潮汐相互作用可以提供一个解释的瞬态现象,如近红外和X射线耀斑从Sgr A*。

英文摘要:

The discovery that the Galactic centre emits flares at various wavelengths represents a puzzle concerning their origin, but at the same time it is a relevant opportunity to investigate the environment of the nearest super-massive black hole. In this paper we shall review some of our recent results concerning the tidal evolution of the orbits of low mass satellites around black holes, and the tidal effect during their in-fall. We show that tidal interaction can offer an explanation for transient phenomena like near infra-red and X-ray flares from Sgr A*.
